By removing water as it forms.

Question 5

Which of the following is a product of the reaction between acetic acid and isoamyl alcohol?

Accepted Answer

Isoamyl acetate

Question 6

If the esterification reaction is represented as $ \mathrm{CH_3COOH} + \mathrm{C_5H_{12}O} \rightleftharpoons \mathrm{CH_3COOC_5H_{11}} + \mathrm{H_2O} $, which change will NOT shift the equilibrium toward ester formation?

Accepted Answer

Adding more water to the reaction mixture.

Question 7

Which of the following statements about esterification is correct?

Question 10

In the context of Le Chatelier's Principle, what will happen if water is continuously removed from the esterification reaction mixture?

Accepted Answer

The equilibrium will shift toward the formation of more ester.

Question 11

Which of the following best explains why removing water during esterification increases ester yield?

Accepted Answer

It shifts the equilibrium toward the products according to Le Chatelier's Principle.

Question 12
